You can use a dual SIM phone, but the Spark SIM must always be in, or set as, the primary SIM slot so that it has access to the UMTS/3G radios. If the Spark SIM was in, or set as, the secondary SIM slot then it wouldn't work at all. It seems that even on newer dual SIM phones, only one SIM can support 3G/UMTS at a time. Spark is 3G/UMTS only.

Dual sim works great for me with a vodafone and 2degrees sim in the handset. Get calls on both no worries, and quick menu selection to change the 3/4g over to 2 degrees when I find I am low on data on vodafone or in the rare spot where they have nothing useful but 2degrees have signal.

The sim that I am not using for data sits on a 2g network, but that largly seems fine for the odd phonecall or SMS that comes in.

You're suggesting there is a phone that can manage 3/4G on both sims? (Although not at the same time obviously)

3G / 4G on both SIMs but not at the same time is common. My Mi 4i does it. However sbiddle last week in a post gave the name of a Chinese one that does both at the same time.. Can't remember the name though..

I'd forgotten about the One Plus Two, it has a couple of areas they've seemingly skimped on to keep the price down, but does seem like a good option. Since owning the Note 4, and having such a great camera, i'm now finding it difficult to consider anything that doesn't stack up quite so well in that department, and that seems to be one thing the OP2 lags behind on slightly?

It seems you and richms both own phones that can utilise 3/4G in the secondary sim slot, but Stu and sbiddle thought that wasn't possible. Hmm

Stu: Then as above, but get the phone you want as well because um.... The old phone err won't work on the Spark network? (Yeah we know it will, but we won't tell your better half!)

Or buy the better half a new phone as well. My wife wants an S7 Edge, so I'm up for two of them!

Unfortunately, she may not be very technically literate, but I don't think I could convince my current phone won't run on Spark.. was a good idea though ;)

The camera in the OP2 is about 12mp. It is not the same camera used in most other phones and I've found that it handles many lighting situations better. It's a pretty good camera.

Here are two shots of the same scene in Greenlane from a few months ago.

For those with the OP2, has the lack of band 28 been a problem for you? Are you running the US or Global models? For $599 from parallel importing sites, it seems pretty cost effective

I'm officially unsure now, some are saying both sims can do everything, some say no handset can do 3G/LTE in the secondary. Seems the OP2 can do both as there are a couple of people here with the device to confirm it, but other than that i'm clear as mud on the situation

To clarify, the Sony, Samsung, etc can do 3G/4G in both slots but only in one at a time. It doesn't matter which slot you put the SIM cards in, you choose in the software which slot is 3G/4G and which is only 2G and you can swap these via the settings menu whenever you want.

I have an LG G3 Dual Sim (D858HK) with 4G/3G/2G on SIM1 and 2G on SIM2 I'm playing around with. I've used 2 Vodafone SIMs and it will only detect SIM1: I swap the SIMs around and it still does not detect SIM2. But when I insert a Spark prepay SIM in SIM2 and one of my Vodafone SIMS in SIM1, the G# sees both and I can activate both...

Does this mean I can't use SIMs from the same provider in the same Dual SIM?

FYI. Just bought the Moto G4 Plus from PB Tech at the boxing day sales as I wanted a vanilla interface dual SIM phone. My normal configuration is SIM1 Skinny LTE and SIM2 Optus AU roaming on 2D or Vodafone (used for password resets from AU) As a part of the run up of this phone I notice when Skinny and Optus SIMs were both in I saw 4G on the Skinny SIM and 3G on the Optus SIM. I changed the Optus SIM to a Spark SIM and the they were both online and I could receive calls on both SIMs but could only call out on the one that was set as default. So I guess you can add this to the list of phones that will do 3G the second SIM for calling on Spark / Skinny

I'm using a Mi 5 and running 2 x Spark SIMs at the same time. They can both receive/send txts and calls. You can select which card you want to use for mobile data. It's the only phone I have found so far that will let me use both Spark SIMs at the same time which are both 3G WCDMA minimum.

Previously had a dual SIM S7 but could only have 1 Spark card active at a time while the other had completely no signal as it automatically set itself to 2G Only.
